I see them a lot though and don't think they look especially odd. I guess as long as you're wearing a darker tan khaki and not the almost white ones it would be fine and I wouldn't think it looks out of place.

I wear them often, and I wear them year-round. I have them in different shades of brown and grey, and I also have a black pair. I wear them and jeans all fall, winter, and spring, as well as sometimes in the summer. I also wear them to Bath and Body Works when I work there, as that is one of our "uniform" choices.
